1 Claim.

to improvements in apliquids to the skin, hair or the like, and has for its object the provision of an improved form of applicator made of a non-absorbent material such as glass, porcelain,

synthetic plastic or the The principal object like. of this invention is the provision of an applicator for liquids, made of non-absorbent material in which a considerable quantity of liquid can be applied to the skin quickly and without spilling.

A further object of vision of an improved is sanitary, can be readily cleaned and is inert to the action of chemicals.

Further objects of the invention will be apparent from the specification and drawing inwhich Fig. 1 is a front elevation of the cap applied to a liquid container.

this invention is the proform of applicator which Fig. 2is a perspective view of the cap with the operative end attached.

Fig. 3 is a fragmentary section on line 3-3 in Fig. 2, and

Fig. 4'is a section on line 4-4 in Fig. 2.

The size of these apertures is very important in the making of an applicator of this kind as on the size and depends the satisfactory application of which the are too small, then through the these apertures l4 shape of the apertures delivery of liquid in the device is employed. If

If these apertures i4 liquid in the apertures is the applicator does not I have found by experiment that, for a given preparation, 'ship between quality of the liquid us there should be a definite relationthe specific gravity and the flowing ed and the size, depth and number of holes employed in this form of applicator.

' For example, I have found that the scale below attraction in the bores indicates, generally, the ratio of optimum bore diameter to specific gravity, for a liquid deodorant consisting of:

Aluminum chloride (crystalline) 8 lbs. av.

Specific gravity of 1.0000 liquid requires hole of .0555" diameter. 10 Specific gravity of 1.1256 liquid requires hole of .0625" diameter.

Specific gravity of of .0666" diameter.

Specific gravity of 1.5000 liquid requires hole 15 of .0832" diameter.

Specific gravity of 1.7000 liquid requires hole of .0943" diameter.

Specific gravity of of .1110" diameter.

Specific gravity of 2.2500 liquid requires hole of .1248" diameter.

These figures are, of course, subject to some latitude where preparations of other composition are concerned, the viscosity of the prepara- 25 tion employed, 'as well as its wetting property for 'thematerial of the paddle-like. applicator being additional factors entering into the determination of the optimum diameter for the bores I4. As is obvious, where the material is quite 30 viscous or has great afiinity for the paddle material, the coeificient of adhesion of the preparation, or more properly, the coefficient of capillary 14, will be greater. The bores l4 should, accordingly, be of larger size than otherwise indicated by the specific gravity of the preparation, in order to facilitate discharge and proper distribution of the preparation upon the skin surface.

It is evident that applicators of this kind can be made of materials very resistant to the action of chemicals or solvents, preferable materials being glass, porcelain or synthetic plastics or resins.

Although I have described a preferred embodiment of my invention, it is apparent that the 4 size and number of the holes may be varied from time to time and also that in some cases it may be possible to make an operative applicator of this type without having the apertures extend entirely through the body of the applicator.

1.2000 liquid requires hole 2.0000 liquid requires hole Having fully described claim is:

An applicator for distributing body deodorant or the like upon flat skin surfaces, comprising: a handle member, a broad, rigid, double-faced blade carried by said handle member and constituting therewith a paddle-like structure, and well means in said blade for holding a quantity of lotion and automatically feeding the same to my invention, what I either face of said blade when brought into fiat contact with the skin surface to be coated, said well means consisting of a plurality of parallel non-communicating bores each having a diameter of approximately one-twelfth of one inch and extending completely through said blade from face to face thereof so as to be individually chargeable by simple immersion of the blade in lotion and automatically gradually dischargeable by flat contact of either blade face with the skin surface to be treated.
